While most Hollywood stars are working on their beach bodies, Adam Sandler threw caution to the wind this week. The “Grown Ups 2” star was spotted Monday afternoon at the Brooklyn Diner on West 57th Street, where he ordered a “piled-high hot pastrami sandwich” and “a side of pastrami to go with it,” our spy reports. Sandler was having lunch with his family, so we hope he shared some with his kids. The comic appeared on “The Late Show With David Letterman” the following night before his film screened at the AMC Lincoln Square, and showed a clip of himself being attacked by a cheetah on safari (who apparently wanted a Sandler sandwich, with a side of Sandler).
